The Given

The extension and renewal of cultivar assortment is one of the key elements in the improvement of apricot production. Competitiveness can only be achieved by planting cultivars which meet all market requirements and yield reliably under the environmental conditions of the given production site. Beside breeding programmes, the range of cultivars can also be extended by the domestication of foreign cultivars. Most apricot cultivars have low ecological tolerance, therefore, cultivars improved or developed in other countries should only be involved in production after due consideration. The suitability of such cultivars has to be examined for several years. Foreign apricot cultivars have been tested in our cultivar collection for over 10 years. Hereby, the most important aspects of market value and the adaptability to the environmental conditions of the production site are demonstrated. According to the results of our examinations the production of early ripening 'Orange Red' and `Goldrich' can be promising in Hungary. From cultivars ripening in the peak season only those are expected to be widely produced which differ from Hungarian cultivars or surplus them in some respects. From the cultivars examined 'Harogem' which ripens at the same time as `Gönci magyar kajszi' has remarkably aesthetic fruits with glossy surface, while the large fruits of `Hargrand' has firm pulp. Late ripening cultivars have significant importance in the northern border of production. According to our examinations the cultivars 'Callatis', `Comandor and `Sirena' are applicable in Hungary to extend the harvesting season.

Some physicochemical parameters related to ripening and their relationship with ethylene were studied in date fruits ( Phoenix dactyliferaL. type Negros). Dates were harvested and classified into sixteen ripening stages according to their color, ranging from yellow-greenish to dark brown. Fruit firmness decreased through the different ripening stages, while the ripening index, expressed as the relation between soluble solids and acidity, increased. The greatest loss of fruit firmness correlated with the greatest increases in both polygalacturonase and •-galactosidase activities. In early ripening stages, a small peak in ethylene production was detected, followed by a peak in respiration rate, suggesting that a date could be considered as a climacteric fruit, with the plant hormone ethylene being responsible for changes in color, fruit firmness, soluble solids content and acidity.

It is well known that an effective way to improve the quality attributes of food is the use of coatings. Moreover, there is evidence of the use of dairy byproducts to design coatings to improve the shelf life of food products. This study was conducted to explore the effectiveness of a film forming solution containing whey protein–pectin complex enzymatically reticulated by transglutaminase (TGase) applied as a coating on eggshells to preserve the internal quality of eggs stored under environmental conditions (25 ± 1 °C and 35% HR) during 15 days storage. Eggs properties tested included yolk index, albumen and yolk pH, albumen CO2 content, water loss, shell strength, and microbial permeability through the shell. The results showed that the coating maintained a higher yolk index and albumen carbon dioxide content, reduced the weight loss and increased both albumen and yolk pH values with respect to the uncoated eggs. All coated eggshells showed greater strength than those of uncoated eggs. Moreover, by using Blue Lake dye penetration method we demonstrated that the coating reduced the Blue Lake dye penetration confirming the effectiveness of the coating on the reduction of post-wash bacterial penetration. These results suggest that the studied coating can be useful to preserve internal egg quality but also to reduce the breakage of eggshell and egg microbial contamination. Based on this result we can conclude that the coating made with whey protein–pectin crosslinked by TGase could be an effective strategy to increase the shelf life of eggs preserved in environmental conditions and to reduce economic losses due to the eggs breakage during their marketing.

Pineapple is one of the most cultivated tropical, non-climacteric fruits in the world due to its high market value and production volume. Since non-climacteric fruits do not ripen after harvest, the ripening stage at the time of harvest is an important factor that determines sensory quality and shelf life. The objective of this research was to investigate metabolite changes in the pineapple ripening process by metabolite profiling approach. Pineapple (Queen variety) samples from Indonesia were subjected to GC-MS analysis. A total of 56, 47, and 54 metabolites were annotated from the crown, flesh, and peel parts, respectively. From the principal component analysis (PCA) plot, separation of samples based on ripening stages from C0–C2 (early ripening stages) and C3–C4 (late ripening stages) was observed for flesh and peel parts, whereas no clear separation was seen for the crown part. Furthermore, orthogonal projection to latent structures (OPLS) analysis suggested metabolites that were associated with the ripening stages in flesh and peel parts of pineapple. This study indicated potentially important metabolites that are correlated to the ripening of pineapple that would provide a basis for further study on pineapple ripening process.

The United Nation’s Food and Agriculture Organisation have indicated that higher contamination of agricultural produce with mycotoxins is associated with the alterations in the weather conditions. The aim of the current study was to quantify mycotoxin contamination on buckwheat grain at early and complete ripening stages and to estimate the effects of the weather conditions on mycotoxin occurrence as well as to consider natural measures that could potentially reduce mycotoxin contamination in buckwheat products. Mycotoxins deoxynivalenol (DON), T-2 toxin (T-2), zearalenone (ZEA), aflatoxin B1 (AFB1), ochratoxin A (OTA) were analysed in fully ripe buckwheat grain in 2013 and at early ripening stages in 2014 and 2015. The field trials of buckwheat were set up at the Perloja Experimental Station, Lithuanian Research Centre for Agriculture and Forestry. The least concentrations of the investigated mycotoxins in buckwheat grain were found in 2013. Particularly high concentrations of AFB1 (up to ~72 μg/kg) were identified in buckwheat grain at early ripening stages in 2014 and 2015. It is likely that buckwheat grain were contaminated with AFB1 under favourable weather conditions, which were uncharacteristic of Lithuania’s climate in 2014 and 2015: hot weather and drought prevailed during the buckwheat flowering and ripening stages. However, such meteorological conditions were less favourable for the synthesis of DON, T-2, ZEA and OTA mycotoxins in buckwheat grain. The high AFB1 contents found in grain question the quality of buckwheat products. Hulls were 10-fold more contaminated with AFB1 than grain, which suggests that they serve as a protective shield against buckwheat groat, bran and flour contamination with this mycotoxin. Phenolic compounds were found to decrease the risk of mycotoxin occurrence in grain: with increasing concentrations of rutin, quercetin and total phenolics content in hulls and grain samples, the contents of trichothecene mycotoxins were significantly (P<0.05) lower.
